ROTARY EXCAVATOR.

Specification of Letters Patent.

Patented May 16, 1911.

Application filed June 28, 1910. Serial No. 569,609.

To all whom 'it may concern.

Be it known that I, THOMAS FAHEY, a citizen of the United States,residing at Spokane, in the county of Spokane and State of I/Vashington,have invented certain new and useful Improvements in Rotary Excavators,of which the following is a specification.

This invention pertains to excavators and has for its purpose to providean apparatus so constructed that by a rotary motion it will pick up dirtand gravel and carry the same to a position where it can be picked upand transferred by other mechanical means to a predetermined place. ThisI accomplish by the construction of a cylinder adapted to be mountedupon a horizontal shaft and provided with plows and peculiarlyconstructed apartments with open ports on both sides thereof, suchcylinder being firmly secured to the horizontal shaft and adapted torotate therewith.

Figure 1 is a front view of the cylinder, Fig. 2, is a side viewthereof, Fig. 3, is a broken away rear view thereof and Fig. 4, is asectional view thereof taken on the line 1 -4 of Fig. 1.

The cylinder 10 and the sprocket wheel 11 are firmly secured tothe shaft12, the shaft 12 anchored in a horizontal position is secured to a frameupon trucks for convenience of working and in moving. The cylinder 10 isdivided into apartments 13 separated by walls 26 perpendicular with thefiat sides of the drum, each of which has an entering port 14 and adischarge port 15 and inwardly and centrally inclined foot walls 27. Theentrance ports 141 are on the outside of the cylinder 10 near theperiphery thereof and the discharge ports 15 are on the inside of thecylinder 10 near the shaft 12. Leading to the entrance ports 111 areopen chutes 16, the outer ends of which terminate in plows 17.

In the practical operation of the excavator, the whole is mounted upon aframe, withproper bearings for the shaft 12, and secured to a truck forconvenience in moving. The power of whatsoever kind it is -desired touse, is applied to the excavator by means of an endless chain, operatingover the sprocket wheel 11 secured to the shaft 12. The cylinder 10 isby this means set in motion and rotates with the shaft 12. The plows 17cut into the dirt and gravel in their downward motion and on the upwardmotion thereof the dirt and gravel. by means of gravity pass down thechutes 16, through the ports 14 to the apartments 13 and then along theinwardly and centrally inclined foot walls 27 to and through the ports15 where the same is picked up by any desired convenient means andconveyedto the desired location.

Having thus described my invention, what I claim as new and useful anddesire to secure by Letters Patent, is:

An excavator consisting of a cylinder mounted upon a shaft, and dividedinto apartments with inwardly and centrally inclined foot walls, suchapartments having entrance ports on the outside thereof near theperiphery and discharge ports on the inside thereof near the shaft, openchutes leading to the outside ports, the outer ends of such chutesterminating in plows, the whole adapted to be connected up withcontinuously moving machinery and to rot-ate, substantially asdescribed.

In testimony whereof I aflix my signature, in presence of two witnesses.
